Abstract
The effect of particle size of carbonate minerals (dolomite and calcite) on the kinetics of their interaction with water and ferrous sulphate solution is investigated. It is established that the efficiency of solution neutralization is to a noticeable extent determined by the particle size of the reagent. The application of calcite as a material for the construction of artificial geochemical barriers is preferential over dolomite. In the case when reagent consumption is much higher than the stoichiometric amount, or under lengthy interaction (for example, in filtering dams of artificial geochemical barriers) the particle size of the material has no substantial effect.
